33s it knownthat I, JAMES TL'ANDREW, a

citi'zen of the United States, I residing at Montgomery, inthe county ofMontgomery and State of Alabama, have invented certain new and usefulImprovements in'Safety Appliances for Railroad Cars; and 'I do hereby.declare the following to: be a full, clear, and

exact description of the invention, such as- 0 will enable othersskilled in the art towhich it appertains to make and use the same.

My invention relates to improvements in safety appliances forrailroad-cars; and the object of my inventionisito provide means I 5whereby derailment ,of a train, with itsaccompanying destructiveeffects, "shall be rendered practically impossible.

My invention is applicable not only to rail"- road-cars, but-also .toelectric cars of all de- 29 scriptions and to locomotives.

Other objects will appear "in the description. w 1' With this object inview my invention consists in the construction and combinations'of 2 5'parts, as hereinafter described and claimed.

' In the accompanying drawings,'Fig'ure 1 is a side elevation of theordinary passengertruck, showing my invention applied thereto. Fig. 2 isan end view of the same. Fig. 3 is 0 an enlarged View, partly insection, showing my invention in actual use lifting one of, thecar-wheels. Fig. 4 is across-section thereof on the line 4 4 of Fig. 3.

brake. Fig. 7 is a top plan view 'ofthe same. Fig. 8 is a perspectiveview of the inner sup portin -brace. Fig. 9 is a perspective View o o fthe supporting-bracket introduced into the journal-box. F ig. 10 is a-siidegelevation ofa modified form ofmy inventions; .Figfll I is alongitudinal sections-lot said? modified form, and Fig. 12 is facross-section of the same.

' .In th'edrawin s, a represents an ordinary passenger-truck, avmg theusual side beams, journal-boxes, sprlngs, &c.,. which need no further.description. Underneath each j our- 5o rial-box two movable shoesfsuch'as bland c,

are located, there being therefore eight of Fig. 5 is aperspec-- may beeasily applied to the existing trucks without any alteration and withvery slight expense. Said shoes are shown in perspective. in Fig. 5, andeach of them consists of a camshaped portion d, provided with a roundedlower edge e and rounded ends, such as f. It is also provided with'aflange g, located on the same side'of the car as the correspondingflange on the car-wheel. The in nershoe, such as 0, has a flange, suchas h,

extending the complete lcngthof the shoe and of practically the samedepth throughout, while the flange on the outer shoe practicallydisappears at the center and enlarges near the ends, as shown in Fig. 3.The reasonfor spread track the outer shoe-to fall upon the rail when thewheel runs ed and to support the car, the shoe being then thrown up intothe position shown in Fig. 3, thus bringing the wheel back into positionon the rail after the spread portion ofthe track has passed of twocastings, the main portion (1 having an these shoes to every truck.These shoes having the flange on the outer shoe 'constructed inthis wayis "to allow in case of The shoe is constructed, as shown in Fig. 5,

upwardlyrprojecting ear-i, a depression 1 for the reception of thepivot-pin, and holes m for the reception of the. springs hereinafterreferred to- The other piece of the shoe con- ,sists of anupwardly-extending perforated ear '0 1 and sidewise-extending portionsp, which fit into corresponding depressions cut in the'top of theshoe.The detachable piece is heldin place by means of bolts 1*. In Fig.

. 5 the detachable piece is shown on the inside of thej hoe; but itcould be placedon the outside of the shoe, if preferred. Theshoes areheld in position by means of, a supplemental beam is. (Shown in Figs.- 1and 3.)

This is attached by bolts t to the regular equalizing-framed the truckand to the out-' side beams 14 and also by boltsthrough the pedestals vand the frame of the truck. From these beams, if desired to strengthenthe construction, a collar may extend from beams 8 completely around thejournal-boxes. These beams-s are provided with'a downward rojection wfor the reception of the pivot-pin x, which runs through theears i and 0on the shoe. The pin a: is welded to the beam 'i,- i

' thereby forming an integral part thereof." In each of the holes 'm-isfastened, by means at its upper end to a yoke of a pin, a tension-springy,

of the car will rock the shoe back into-the pof sition shown in Fig. 3,which will have the ef-' fect .of automatically raising the car-wheeland truck out of'harm s way and at the-same I truck-Wheels; and "fourinside.

For example, if thetrain should be derailed and moved to the right from the position shownin Fig. 2 the shoe 0 would engage one of the l rails and the oppositeshoe 1) would engage the other of the rails and immediately lift thewheels above the rails and apply the brakes I automatically, aspreviously described, and the shoes I) -and 0 would slide along therails, assisting the train to come to stop.

While I have thus described my invention, l

I wish it to be particularly understood that I f 'donot limit myself tothe exact details l shown and described, as these might be va- 1 riedwidely without departin from the spirit of my invention, the essence ofwhich j is that in case of derailment-of any part of E the train thederailed portion is lifted out of harms way, and the train isautomatically stopped before any appreciable harm can be done eitherto-the track or to the rollingstock.
